Summary of "Asymmetric aerobic decarboxylative Povarov reactions of N-aryl α-amino acids with methylenephthalimidines via cooperative photoredox and chiral Brønsted acid catalysis."

An enantioselective aerobic decarboxylative Povarov reaction of N-aryl α-amino acids with methylenephthalimidines through cooperative photoredox and chiral Brønsted acid catalysis is reported. With a transition metal-free dual catalytic system including a chiral phosphoric acid and DPZ as a photosensitizer mediated by visible light, the transformations provided a series of valuable chiral isoindolin-1-ones containing a 3,3-spiro-tetrahydroquinoline-based stereocenter in high yields (up to 83%) with good to excellent enantioselectivities (up to 98% ee) and excellent diastereoselectivity (>20 : 1 dr).

Medical and Biotech [MESH] Definitions

A class of enzymes that catalyze oxidation-reduction reactions of amino acids.

Amino acids and chains of amino acids connected by peptide linkages.

One of a group of nonenzymatic reactions in which aldehydes, ketones, or reducing sugars react with amino acids, peptides, or proteins. Food browning reactions, such as those that occur with cooking of meats, and also food deterioration reactions, resulting in decreased nutritional value and color changes, are attributed to this reaction type. The Maillard reaction is studied by scientists in the agriculture, food, nutrition, and carbohydrate chemistry fields.

Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are linear polypeptides that are normally synthesized on RIBOSOMES.

A series of oxidative reactions in the breakdown of acetyl units derived from GLUCOSE; FATTY ACIDS; or AMINO ACIDS by means of tricarboxylic acid intermediates. The end products are CARBON DIOXIDE, water, and energy in the form of phosphate bonds.
